Abstract

In adult rat hippocampal slices,(2_S,1′_R,2′_R,3′_R)-2-(2,3-dicarboxyxyclopropyl)glycine (DCG-IV) did not affect the basal hydrolysis of polyphosphoinositides but dramatically enhanced (EC₅₀ value = 30 nM the stimulation of [³H]inositol monophosphate (InsP) formation by quisqualate, without substantially affecting the stimulation produced by maximal concentrations of 1_S,3_R-aminocyclopentane-1,3-dicarboxylic acid (ACPD) or carbamylcholine. α-Amino-3-hydroxy-5-methylisoxazole-4-propionate (AMPA) was virtually devoid of activity on [³H]InsP formation, either in the absence or presence of DCG-IV. These results suggest that DCG-IV acts, directly or indirectly, as a positive modulator of metabotropic glutamate receptors in the rat hippocampus.
